IMPRO'VENIENT MACHINE FOR HACKLI-'@ CRE-HSKS. i

The Schedule referred to in these Letters Patent and making psx1; of the name.

To all whom it may concern Be it known that I, GEORGE B. S'rAcY, of Richmond, Virginia, have invented a new' and improved Machine for Hackling Oorn-Husks and I declare that the fol-- lowing is a suiciently full and exact description thereof to enable one skilled in the art to which my invention appertains, to carry it into effect, Areference being had to ,the accompanying drawings, which are made a part of this specifmation.

My invention consists in the arrangement of a succession of toothed cylinders, (preferably of different sizes) and a succession of corresponding toothed concavesin a frame-work constructed for thc purpose, as may hereafter appear.

Inthe accompanying drawings-'- Figure l represents a. longitudinal section of my machine, in a form which I have found to operate with good effect.

Figure 2 is a plan view of a portion of the same.

Similar letters of reference indicate corresponding parts in the drawings.

A, B, and O, represent cylindrical rollers, of the respective diameters of sixteen, fifteen, and fourteen inches.

These cylinders are arranged upon a frame-work, of any proper construction, provided that the frame-work itself shall have a longitudinal inclination in the direction of the cylinder G; or they may be arranged upon a horizontal frame, in such a manner as tol bring -the cylinder B lower than A, and C lower than B, for the purposes hereinafter' described. Iprefer the inclined frame.

.The teeth are arranged c ircumferentially around each cylinder, either sph-ally or in such a manner as will bring each tooth opposite the space between two others in the concave through which it works. The first cylinder and concave'tecth,.heing two inches in length, are so arranged and accommodated to each other, that the chucks, or husks will be stripped into shreds lengthwise. instead of being chopped, or cut transversely' in the process.

The cylinder may be divided into disks, or sections, and, in this case, contain two or more teeth in each disk. i

The second cylinder is constructed as the first, containingsix teeth ineach disk, the teeth being one and one-fourth inch in length. i

The third cylinder is madethe same as the foregoing, having, however, eight teeth in each disk, the. teeth being three-fourths of an inch each in length.

. Underneath each cylinder is a corresponding concave, supplied with teeth as follows:

In the first concave there are two rows, extending l from side to side, each containing eight teeth, equally distant from cach oth'; but the teeth in these rows alternate with each other, so that one tooth of the first row passes between each alternate circumferential row j of the cylinder, and the teeth of the second, or alternate row, pass between those on the cylinder that are not traversed by the first.

The duty of these` teeth, in conjunction with the w cylinder, is to straighten the shocks, and tear them from ltheir` buts, preparatory to their being stripped, shredded, or buckled, by the other cylinders.

The second concave is supplied with two rows of teeth, extending across, from -side to side, and alternating with each other, and one row at the lower edge` of the concave, containing double the number of teeth contained in each of the two rows `inst mentioned, the teeth placed equally distant from each other, and in such a manner as to permit the free revolution of the cylinder above it.

The lteeth in the third concave are arranged in the saine manner as those in the second, and complete the work of tearing the husks, or chucks into shreds,

as begun by the latter.

By having the teeth arranged above described, cutting the husks, or shocks transversely is avoided, and at the saine time the tearing them into shreds is fully accomplished.

These concerns are arranged, in reference to each other, so that the highest end of the concave B isY 'lower or not above thev level of the lcwest'end ci the concave A, and the highest end of the concave C, lower than the lowest end-fof the concave as shown in the drawings. l l

The spaces between the concaves A B C' are sup plied with slats, or bars, G, running parallel with the cylinders, wide enough apart to permit the huts of the husks to pass through between them.

The cylinders all revolve in the same direction, 4 at the rate of twelve hundred, B', fourteen hundred, and Cfatsixteen hundred revolutions per minute.

VThe manner of operation is as follows:

The husks, being placed in at the cylinder A, are taken by the teeth into the concave A', and nia-ire their,

appearance at D, where the heavier parts are forced or drop out through the slats, and the husks are taken on into the concave B by the cylinder B.

` Thisdouble action is accomplished by the angle of elevation at which the teeth of the cylinder B first i strike the. matter, as it comes from underneath the cylinder A, the angle being made such, hy the inclinar tin of the former beneath the latter, as that the teeth of B strike the buts with suiiicient force to throw them ofi' at a'tangent, and through the apertures provided by the -use of the slats G'between the concaves, the husks themselves' being carried forward by the revolutionary iin-cle of the cylinder, and the collective force of the draught produced by the same, into the concave B. The same process is repeated at hv means oi similar arrangements of the cylinder, concave, and slats.

vWhile thnsdcsciihing the construction and arrangement of' the various parts of a machine which lV have ih successful operation, l do not desire to limit myself to the precise details here laid down; but thefollowycessve action set forth,

, in an inclined ing is what I claim as new, and desire to secure kry Letl Letters Patent:

1. I ela-iin the arrangement e!" two er nnn'edrnms, 0r cylinders, so as to produce the results by their snesubstantizrlly as herein' described.

2. I claim the arrangement of 'the series offeylinders plane, or any other relation that will ad? mit the tangential eifeet ofthe stroke of the cylinderteeth upon the buts of the Shneks, as they pass tlnongh lthe machine substantially as and for the purposes explained.

3. Ielaim the slats G and their arrangement relatf tively to the cylinders and coneaves, substantially as v herein described. v

4. .l claim the relative size and arrangement of the teeth in both cylindersnnd eone'zwes, substantially a-s herein represented and described.
